Optical tomography has become an indispensable tool for combustion diagnostics due to its noninvasiveness. However, for a typical tomography system, multiple high-speed cameras are usually required to capture different perspectives simultaneously, which is costly and requires precise synchronization, especially for the diagnostics of supersonic/hypersonic flows. Recently, a single-camera endoscopic tomography system has been proposed to overcome the aforementioned problem [Opt. Commun. 437, 33 (2019) [CrossRef] ]. This work aims to optimize the parameters of the single-camera tomography system such as the number of input ends of the fiber bundle and focal length of the lens. Simulative and experimental studies were conducted. The results show that it has the best performance to register nine projections onto a single camera.

单相机内窥镜层析成像的参数研究

由于其无创性，光学层析成像已成为燃烧诊断中必不可少的工具。然而，对于典型的层析成像系统，通常需要多个高速相机来同时捕获不同的视角，这是昂贵的并且需要精确的同步，特别是对于超音速/超人流的诊断。近来，已经提出了单照相机内窥镜断层摄影系统来克服上述问题。社区 437，33（2019）[CrossRef] ]。这项工作旨在优化单相机断层扫描系统的参数，例如纤维束的输入端数量和镜头焦距。进行了模拟和实验研究。结果表明，将9个投影配准到单个摄像机上具有最佳性能。
